无法对继承对象的属性使用 nMock GetProperty 例程

Question

对象设置期望时，我收到此错误。

当尝试对我模拟的继承自 MembershipUser: ContactRepositoryTests.UpdateTest : FailedSystem.InvalidProgramException: JIT 编译器遇到内部限制的

服务器堆栈跟踪： 在 MockObjectType1.ToString()

在 [0] 重新抛出异常： 在 System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage（IMessage reqMsg，IMessage retMsg） 在System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke（参考MessageData msgData，Int32类型） 在 System.Object.ToString() 在 NMock2.Internal.ExpectationBuilder.On(对象接收器)

这是我正在使用的工具...

VS2008 (SP1) 框架3.5 nUnit 2.4.8 nMock 2.0.0.44 Resharper 4.1

我不知道为什么会发生这种情况。 任何帮助，将不胜感激。

Answer 1

刚刚解决了同样的问题。

请勿将 ToString() 添加到接口定义中。 它已经包含在每个对象中。

        Assert.AreEqual(userId, userFromCaller, "Incorrect userId");

        mockUser.VerifyAllExpectations();

        Assert.AreEqual(userId, userFromCaller, "Incorrect userId");

        mockUser.VerifyAllExpectations();

    }

有有效的犀牛模拟测试。
在rhino模拟测试中，您错过了对预期属性的调用（由Expect.call设置）

从查看代码来看，您似乎在nMock场景中犯了同样的错误
